Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed May 8, 1905. Serial No. 259,364

To all whom, it may concern.-

Be it known that I, CONRAD F. GRAIT, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Improvement in Railroad- Rails, of which the following is aspecification.

This invention relates to a rail in which a base and a tread section areemployed, the two overlapping.

The object of the invention is a rail in which the tread-section whenworn or broken can be readily replaced without replacing the completerail, the new tread being set in po section upon the old base.

Another object is a rail in whic the u e of nuts and the usual form ofiisl1-plates is avoided.

The invention consists in the novel features of construction hereinafterdescribed, shown in the accompanying drawings, and pointed out in theclaims.

In the drawings, Figure 1 is a perspective view of my rail, one basesection being broken off. Fig. 2 is a perspectiveview of an end portionof a base-section. Fig. 3 is an inverted perspective view of a portionof a tread-section, showing a tie-block in place and also inverted. Fig.4 is a perspective view of the tie-plates used in connection with block.Fig. 5 is a perspective view of a In the drawings, A represents thebase-section of the complete rail, and B the treadsection. Hereinafterthese parts will be referred to simply as the base and tread. The baseis grooved along its upper face, as shown at A. At each end the base iscut away, as shown at A and recesses are formed in the sides adjacentthe ends, as at A". Perforations A are formed in the sides of the baseabove the bottom of the groove A for the passage of bolts C.

The tread B has a central depending web B, perforated for passage of thebolts C, as shown at B and the tread A also carries on each sidedepending flanges B, which fit over the sides of the base A, the web Bfitting in the grooves A of the bases, as it will be understood that inassembling the rail the tread and base break joints. A block D isbifurcated to straddle the web B of the tread and is reduced. in.thickness adjacent its longituninal center by being cut away on thesides,

as shown at D. The blocks D rest on the base A adjacent each end of thebase and in the cut-out portions A the cut-away portions D of the blocksalining with the recesses A of the base. plates, fit in the cut-awayportions of the blocks and in the recesses A of the base, one end ofeach plate resting in a recess A of one base and the other end. of theblock in a similar recess in the adjacent base. One plate E of each paircarries on its inner face an integral pin E, which passes through asuitable perforation in the block D and through an alining perforationin the other or opposing plate of t 1e pair and is locked in position bya cotter- )in E The bolts C after being placed in posltion have one endangled or bent, as shown at C in Fig. 5. 7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A rail comprising overlapping tread and base sections, thebase-sections being cut out at the ends and recessed on the sides, ablock fitting said cut-out portions and recessed on the sides, platesfitting said recesses, each plate overlapping the block, and means forlocking the plates in position.

2. A rail comprising a tread having a depending web, a baselongitudinally grooved to receive the web, said base being recessed oneach side adjacent the ends, a block adapted to fit between twobase-sections, and recessed on the sides, said block being bifurcated tostraddle the web, and tie-plates fitting in the recesses of the basesand block.

3. A rail of the kind described comprising a tread portion having adepending web and depending side flanges, a base cut away at each endand grooved to receive theweb, said base and tread having aliningperforations, a bolt adapted to pass through said perforations, a blockadapted to fit in the cut-out portions of adjoining bases, said blockand bases having alining recesses, a tie-plate adapted to fit saidrecesses and having an integral pin adapted to pass through the block,an opposing tie-plate perforated for the passage of the pin, and meansfor locking the pin in place.
